Title: Thermoelectric field emission cathode
Inventor: IDE MASARU
IPC: H01J1/304
Filed: 1992-03-27
Abstract: PURPOSE:To provide a practically useful thermoelectric field emission cathode whose emission angle current density is high but whose total emission current is not so high by providing a specific W single crystal acicular electrode with a cover layer made from Zr and O, and limiting the radius of curvature of the tip of the electrode. CONSTITUTION:In a thermoelectric field emission cathode provided with a cover layer of <100> crystal orientation, the tip of its acicular electrode 1 has a radius (r) of curvature of 0.2 to 0.4mum. The electron emission characteristic of the thermoelectric field emission cathode is determined by intricate factors including the surface configruation, condition, temperature, and field intensity, etc., of the tip of the acicular electrode from which electrons are emitted. The radius (r) of curvature of the tip of the cathode is made smaller than 0.4mum so that higher emission angle current density now required can be obtained. Provided the radius of curvature of the tip of the cathode is in a range as high as 0.2mum and more, the need for a device of a particularly large capacity is eliminated. The thermoelectric field emission cathode is useful for an electron microscope, an electron beam exposing equipment and an electron beam tester, etc., all of which require an electron beam of high intensity.

Abstract: PURPOSE:To reduce the cutting work to reduce the small dia. shaft member dia. by rotating burr generating direction regulation members round a small dia. shaft member of a friction welding part of a large dia. shaft member to the small dia. shaft member and directing generated molten burrs to the large dia. shaft member side. CONSTITUTION:The end faces of the large dia. shaft member 1 and the small dia. shaft member 2 are faced each other and set at the prescribed positions of pawls 3 and 4. Next, the small dia. shaft member 2 is welded to the large dia. shaft member 1 with the prescribed frictional pressure by the movement of a guide 7.

Title: Manufacture of semiconductor device
Inventor: RI SOKUN
IPC: H01L21/66
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To remove causes of defects which are caused by the existence of metal substances on the side walls of spacers formed on the side walls of a gate electrode and on the upper portion of a deactivated region, by analyzing whether metal films remain on the exposed side walls of the spacers and the upper portion of the deactivated region by using an electronic scanning microscope. SOLUTION: Side walls of spacers 22 and a pre-reactive titanium film on a deactivated region are removed by using a chemical substance such as a sulfuric acid solution, to expose the side walls of the spacers 22 and the deactivated region. In this case, since the sulfuric acid solution reacts with titanium components but not with titanium silicide components, a titanium silicide film 26 remains on the upper portion of a gate electrode 18 and the upper portions of n-wells 14. Subsequently, analysis is made by using an electronic scanning microscope imparted with high acceleration voltage as to whether or not metal such as titanium, exit on the exposed side walls of the spacers 22 and the upper portion of the deactivated region. At the time of this analysis, the acceleration voltage imparted to the filament of an electron gun is maintained at a level so high as around 10-30 kv.

Abstract: PURPOSE: To make it possible to hold the high impedance and high level of an input node at the level of an electric power source by employing a circuit, consisting of a delay circuit and MOS transistor, at the high impedance node.  
     CONSTITUTION: Simultaneously with the activation of input signal IN, control signal ϕ 12  changes from level "0" to level "1" and signal IN is transferred to node OUT 11 . At the same time, node N 13  is charged through MOSFETQ 11 . After the charge, output node N 11  of delay circuit B1 changes from level "1" to level "0" and output node N 12  also changes from "0" to "1" to setting node N 13  higher in level than the electric power source through capacitor C 11 . As a result, node OUT 11  is coupled with electric power source VDD in the low impedance state through MOSFETQ 12 . In this state, node OUT 11  forms a holding circuit to electric power source VDD and even when MOSFETQ 13  is turned off by holding signal ϕ 12  at level "0", node OUT 11  can be held at the electric power source level.
